TIRE.

Specification of Letters Patent.

Patented llilalr. 9, 11915.

Application filed June 16, 1914.. Serial No. 845,454.

each other, the several series of plates forming a practically non-puncturable armor 1ncorp rated in the fa ig. 3 is a transparent perspective viewpf a. section of the tire showing the relative arrangement of the plates.

eferring to the drawings A each other and in several superimposed laytime,'an apparent blister Wlll appear in the tread or side Wall of the tire and when the a pneumatic tire constructed in acsame is opened up, hundreds of these small disks pour out therefrom, showing that the disks have cut their way through the tire fabric and accumulated, leaving portions of the tire unprotected by said disks and therefore subject to puncture by nails, tacks and other sharp objects.

n carrying out thepresent invention, I make each of the puncture-proof plates as shown in Fig. 2, B designating generally one of said plates. The main body 1 of the plate shown resembles a disk but departs therefrom in that it is provided with a I tongue 2 projecting from one edge thereof,

cut from the body 1 to form the recess 3. W0 or more layers or series of such plates are incorporated in the fabric of the tire as illustrated in Fig. 1, the layers being superimposed one upon the other and the plates of each layer being arranged in overlapping or break joint relation to each other so that the projection 2 of one plate will be in radial alinement with and cover the recess 3 of another plate. The layers are so arranged relatively to each other that the plates thereof will bear an overlapping or break joint relation and thus it is practically impossible for a nail or like object to pass as it is certain to be deflected by one or more plates B.

he plates under the arrangement hereinabove described may either be incorporated icy mav 1n the fabric of the-tire itself or tl be incorporated in a strip of rubber and textile fabric, \ihich strip may be incorporated in the main body or carcass of the tire during the vulcanizing process.

It will be understood that the projections 2 and recesses 3 not only serve to elongate the outer marginal edge of each plate but they serve as keys or bonds when the rubber and fabric is rulcanized around t e vulcanizing process, the rubber i panded so as to enter the recess 3 and fully occupy the same, the rubber on both sides of each plate B flowing togetl1er.and combining under the vulcanizing process. In the same Way and for the same reason the projeetions 2 are enveloped in the rubber and fabric.

What I claim is I. A pneumatic tire having incorporated therein a plurality of layers of punctureprooi plates so arranged relatively to each other that the plates of one'layer break joint with the plates of the next layer, each plate being provided with a projecting tongue at one edge and a recess of corresponding shape opposite said tongue, the plates of one layer being so disposed with relation to the plates oi the adjoining layer that a tongue of one plate lies in radial alinement with and covers the recess of another plate 2. A pneumatic tire having incorporated in the fabric thereof a plurality of layers of puncture-proof plates so arranged relatively to each other thatthe plates of one layer break joint with the plates of the next layer,

alineinent with and covers the recess of another plate, the plies of the fabric being 'vul canized together around and. between the plates of each layer and through the said recesses in the plates.

In testimony whereof I ailix my signature in presence of two Witnesses.
